Configuring WebLogic Server 12.2.1.3 Diagnostics Framework policies and actions

By | Application integration & Middleware | No Comments

Configure a Policy-action (new name for watch-notification) to send a JMX notification when the monitored WebLogic Server is having stuck threads or high memory usage. We will use a simple JMX notification listener program which can process WLDF JMX notifications. In this case, it will simply print the contents of the notification. For simplicity, we will have only two servers in the domain, AdminServer (admin-server) and Server1 (managed-server). We will configure WLDF on the Server1…

DOAG 2017 – Middleware: Automation and Docker container streams

By | Application integration & Middleware | No Comments

End of last Month I participated as presenter to the DOAG 2017. It was interesting to see the growing interest on the automatic deployment tools. I presented the way the Fusion Middleware cloning can be used with such automation tool to lower the time needed to install an environment. The Fusion Middleware cloning is based on a master installation where all patches, configuration, system components are installed and configured. Thus, a real time reduction when…

How to rename an existing Fusion Middleware WebLogic Domain

By | Application integration & Middleware | No Comments

Some times it happens that we need to rename an existing fusion Middleware WebLogic domain. I was asked to do such on a Fusion Middleware Reports & Forms environment. I took some time to check how this can be done and did some testing to confirm it works as expected. The difficulty is not the WebLogic Domain itself as a WebLogic domain can be created quickly but it is time consuming if the complete configuration…

Configuring Fusion Middleware 12C Reports Server with Single Sign On and External LDAP server

By | Application integration & Middleware | No Comments

Most of the time when the Reports Server is configured with an Single Sign On Server, it uses the same external LDAP server as the Single Sign On Server. In our case, we used an Oracle Access Manager as Single Sign On and an Oracle Internet Directory as LDAP server. Of course the Fusion Middleware needs to be configured with the external LDAP server. This means an Oracle Internet Directory authenticator provider declared in the…

Using WebLogic 12C RESTful management for monitoring WebLogic Domains

By | Application integration & Middleware, Oracle | 4 Comments

WebLogic 12.2.1 provides a new RESTful management interface with full accesses to all WebLogic Server resources. This interface offers an alternative to the WLST scripting or JMX developments for the management and the monitoring of WebLogic Domains. The following of this blog provides a few examples demonstrating the simplicity and the efficiency of the REST requests. WebLogic Server State When checking a WebLogic Server state, we are interested in the state and in the “ActivationTime”…

Apache JMeter and Cross-Site Request Forgery (CSRF) token management

By | Application integration & Middleware | 2 Comments

This token might be unique for each request and thus it blocks us from using the recorded JMeter test session off the shelf. This blog will describe how this CSRF feature can be handled in JMeter. How to implement this feature The solution is to identify and extract the CSRF token from the response…

Documentum story – How to display correct client IP address in the log file when a WebLogic Domain is fronted by a load Balancer

By | Application integration & Middleware, Entreprise content management | No Comments

The Load Balancers do not provide the client IP address by default. The WebLogic HTTP log file (access_log) does not provide the client IP address but the Load Balancer one. This is sometimes a problem when diagnosing issues and the Single Sign On configuration does not provide the user name in the HTTP log either. In most of  the cases, the Load Balancer can provides an additional header named “X-Forwarded-For” but it needs to be…
